Abstract
A camera optical lens is provided, including from an object side to an image side: a first lens having positive refractive power; a second lens having negative refractive power; and a third lens having positive refractive power, wherein the camera optical lens satisfies following conditions: 0.75≤f1/f≤0.95; 1.20≤f3/f≤2.00; 0≤(R1+R2)/(R1−R2)≤0.80; −3.50≤(R3+R4)/(R3−R4)≤−1.50; −8.00≤(R5+R6)/(R5−R6)≤−2.50; and 1.50≤d5/d4≤4.00. The above camera optical lens can meet design requirements for large aperture, wide angle and ultra-thinness while maintaining good imaging performance.
